.to remove the lamp `black and smaller particles of dust from gas to be purified.

The apparatus covered by my invention comprises a scrubber chamber through .which the gas to be purified is causedto pass, a drier chamber which receives the puritied gas delivered from' the scrubber chamber, and from which the gas is delivered to the distributing mains or to other purifying apparatus.

The gas in passing through the scrubber chamber is caused to'tlow through a series of screens over and through which waterl is caused to flow in a direction opposite to the flow of gis. Under such conditions the gas carrying the most recrement comes in contact with water which has been utilized in partially scrubbing the gas and the cleanest comes 1n contact with the cleanest water.

In the drawings accompanying this application and forming a part thereof; Figure l. is a sectional elevation ot' an organized apparatus embodying my invention; and,

Fig. 2 islasectional elevation oli' a detail ot' my invention. f

A scrubber chamber 3 and a' drying chamber l ai" inclosed Within a shelli, which is forme` of a number' of annula'v sections superimposed' and secured together by flanged connections, or inany other suitable maiineix The shell 5 is provided near. the

` bottom with an inlet port 6, which cour municates through suitable piping 7 with source o f-gassupply and delivers the gas to the lower portion. ofthe scrubbin ehamber 3. A number of partitions 8, w lich are parallel to each other and to the verticalv walls ofthe chamber 3, are located within the chamber above the inlet port 6. A Water supply pipe 9 extends through the shelll 5 into' the upper portion of the chamber above the partition 8 and delivers vater from a number of communicating jet-s 10 to the chamber 3. The vertical walls oi. the chamber and partitions 8 are provided with Specification of Letters Patent. pplicatitm filed February 14, 1902i. Serial No. SoM-34e..

in the county of Allegheny and raantea aus.. es., imo.,

brackets l'l which coperate in supporting r the screen holding frames -Each trame. l2 is rectangular in shape and is provided with means for securing one or more thick ness'es of screening 13 in place `across it. rlhe screening utiliz/.ed with producer gas is preferably burlap, but other materials may be utilized. A strip of compressible packing material llt is secured around the ontn side ot' each frame 12 andis adapted to pack the joint between the frame and its mounting members.

Each iframe is supported on one of the brackets il and is adapted to rest against the adjacent wall or partition, assun'iing an inclined position and thereby presenting a series of perfor-ations through which all the gases passing through the paralel walls must flow. The water jets 10, which are located in the upper portion of the chamber 3, are adapted' to discharge a spray of Wat-er lor other liquid onto the top screen of cach series located between the parallel partitions and the frames are inclined at such an angle that the liquid will travel over the faceoi thc screen rather than seep through it until cel it reaches the edge of the screen and will uniformly flow through onto the upper edgeoi the next screen. the' top ol' which rests diret-ily belowL the 'supporting bracket. With such an arrangement the water will zigzag through the narrow' passages and :will tinally be discharged by the lowest screen of the series into a receptacle formed in the bottom partof the chamber 3 below the inlet port G. The receptacle is provided with au overflow pipe 15 which communi-A cates witlra sump pitor any suitable drain.i

.t port 16 located atthe top of the scrub-5 ber chamber 3 communicates through suitn 9,5

' able pipingfl' and a port; 18, :termed `in the.

head portion ot the apparatus, withthe dry ing chamber d. pipe i9 `commindicates with the piping l? and extends do'uuiwardly through 4the chamber e. The gas, after learing the purifying chamber, is condueted'by' the piping 17 and the pipe 19 to the logirttomv portion of the drying .chamber d, and4 after being discharged from the pipe 19,"t-ravels upwardly through the chamber 4l; and is discharged from an ont-.iet port 2U, -which is located in the ltop portion oit the drying chamber. 'The port 2() communicates through suitable piping QQ with the gas delivering mains or. with other puri-tying apparatus=k overflow l5.

The construction shown involving; un

angle Valve 9A: in connection with elbow li' is applicable only to a scrubber niade up of 'two or more sections so arranged that, either may be lcut out .of service for cl-ianingwhile the other sections ere in operation.- ln a single scrubber, the elbow of piping- 17 would be bolted to the partition 25 between chambers 3 and 4, said partition having an opening coinciding` with the elbow und located above the writer sprays in chamber 3, thus doing away with the :ingle valve 24.

The scrubber chuinber 3 is preferably rectangular in shape and is preferably provided with a swinging door or other opening along one side, through which the screens may be introduced. to the chamber an"1 which, when it is closed, will cooperate w; h the packingr material 14 uround the trame portions .l2

of each screen to form a tight joint. Under such. conditions all the gas entering the ap paretus through the port 6 is caused to pass through a number of screens which are washedwvith a continual tlow of scrubbing' liquid. It is my intention to employ in this scrubber screens of suoli characteristics as will allow the Washing liquid to form films covering the several openings in 'the screen. The size of the individuel opening will, therefore, be determined by the material from Awhich the screen is mede as Well as by thenuture of the liquid used in Washing,

the cohesive tension of the liquid 'being the l l l i I l l l I i some gases, it is found that the particles nioistcned and retined by the liquid are Washed back through the screens against the flow ol gas. Under very favorable conditions, therefore, this scrubber would bc'selit cleaning, but to provide for such cleaning of screens as may be nnule necessary by less favorable conditions, doors ure provided in the scrubber shell, as before mentioned, through which the several screens may be easily removed for cleaning.

It will. be apparent that the apparatus may be constructed in various ways. In thcdrawingl the parallel partitions 8 are shown as constructi-id otl metal, thtl brackets ll bcing integrully toi-ined on, them. It inay be found desiruhlc in practice to utilize partitions, casing und 'traineof Wood or other material. llt muy also be found desirable to inodiify the construction ot the drying churn'- ber, and all these changes may be made without depuirting freni the spirit otiny in` vention;

Wilhoit I cluini is:

A gas purilicr comprising a casing, a plurality of partitions vertically arranged with` in said'casing and having;` rests und screens snpl'iorted by said rests and alternately inclined in opposite directions, the said screens having unobstructed spaces between them.

ln testimony whereof, l have hereunto subscribed my name this ary, 1907.
